Highlighted color scale.

This scale blends the hue_pal and grey_pal palettes from the scales package. The "highlighted" elements, selected by position, use the hue palette; the other elements use the grey pallete.

scale_colour_focus(pos, ..., h = c(0, 360) + 15, c = 100, l = 65,
  h.start = 0, direction = 1, start = 0.2, end = 0.8,
  na.value = "red")
